A planning model
Higher ROAS does not always mean higher total profit.
A smaller campaign can report a stronger ROAS while producing less total contribution than a larger, less efficient campaign. This planner makes spend, implied CPA, revenue, orders, and contribution visible together.
Every scenario is an explicit assumption. Enter the ROAS you believe each spend level can sustain, or use CPC plus CVR to derive a scenario ROAS first. The five guardrails compare entered thresholds and evidence; they do not infer an optimal budget, prove incrementality, or assume efficiency remains unchanged during scaling.
